我试图分析一下我有两个班级的情况.一个类是ProcessImpl,它是起点并在内部调用其他子事务.我不知道什么是错误的.
processImpl正在导入一些东西并将相关数据写入数据库.

Specs

@H_301_9@

Spring-orm版本：3.2.18.RELEASE.

JDK版本：1.8.

Db：H2(记录任何db相同的性能).

Issue

@H_301_9@

如果我从ProcessImpl.processStage()中删除@Transactional,则该过程需要约50秒
如果我从ProcessImpl.processStage()保留@Transactional,则该过程需要大约15分钟.
不知道为什么会这样.
我一直试图解决这个问题,但没有运气.请看下面的代码.

需求：
完整的processStage()应该完全或完全回滚,即使其中一个子事务失败.

Fyi：我也收到很多消息：“参与现有交易”.试图通过将propagation = Propagation.NESTED添加到processStage()但没有工作来克服这个问题.

ProcessImpl Class.

@H_301_9@

public class ProcessImpl {

    /*This is the big transaction that calls other transactional stuff from MyServiceImpl
    * This is starting point you can say for the process...
    * 
    * If we remove @Transactional from here the process is lightning fast 
    * With transactional : 15minutes
    * Without transactional : 50 seconds
    * */
    @Transactional
    public void processStage(){
        MyServiceImpl mp = new MyServiceImpl();
        //do some stuff
        mp.doWork1();

        //do more work
        mp.doWork2();

    }

}

MyServiceImpl Class

@H_301_9@

class MyServiceImpl{

    @Transactional
    public void doWork1(){
        Object o = doChildWork();
        // and more stuff
        //calls other class services and dao layers
    }

    @Transactional
    public void doWork2(){
        //some stuff
        doChildWork2();
        doChildWork();
        //more work
    }

    @Transactional
    public Object doChildWork(){
        return new Object(); //hypothetical,I am returning list and other collection stuff
    }

    @Transactional
    public Object doChildWork2(){
        return new Object(); //hypothetical,I am returning list and other collection stuff
    }

}

此外,我将在这里获得自我调用问题,这在Transactional中是不可取的？
